From the aspect of the quantum information theories, various quantum entropies are possibly computed at each stage, which ensures the emergence of the entangled states in the intermediate step. If a single qubit quantum teleportation is near the computational basis, the quantum measurement is domina

Most cancer cells utilize aerobic glycolysis irrespective of their tissue of origin. The alteration from oxidative phosphorylation to glycolysis – called the Warburg effect – is an universal phenomen and has now become a diagnostic tool for cancer detection.

Energy transfer in material solids is driven primarily by differences in intensive thermodynamic quantities such as pressure and temperature. The crucial observation in quantum-theoretical models was the consideration of the heat capacity as associated with the vibrations of atoms in a crystalline

Tomasetti and Vogelstein show that the lifetime risk of cancers of many different types is strongly correlated with the total number of divisions of the normal self-renewing cells maintaining that tissue’s homeostasis. These results suggest that only a third of the variation in cancer risk among t

Rieper, Anders and Vedral modelled the electron clouds of nucleic acids in a single strand of DNA as a chain of coupled quantum harmonic oscillators with dipole-dipole interaction between nearest neighbours. As a main result, the entanglement contained in the chain coincides with the binding energy

Quantum tunnelling is a phenomenon which becomes relevant at the nanoscale and below. It is a paradox from the classical point of view as it enables elementary particles and atoms to permeate an energetic barrier without the need for sufficient energy to overcome it. Tunnelling is being of vital imp

Bohm used the term ‘holomovement’ which is an unbroken and undivided totality and carries an implicate order which is he totality of an order including both the manifested and non-manifested aspects of the order. Non-local quantum phenomena reside in a subtler level than quantum level that is th

Cancer is a group of almost 200 diseases that involve variety of changes in cell structure, morphology, and physiology. Cancer phenotype is underlying several alterations in cellular dynamics with three most critical features, which includes self-sufficiency in growth signals and insensitivity to in

Under its icy crust, Saturn’s moon Enceladus conceals an global ocean of liquid water. A detector on the Cassini space probe detected ice particles propelled from Enceladus that contain high concentrations of organic substances. They exhibit the structures typical of highly complex macromolecular compounds. „This is the first evidence of large organic molecules from an extraterrestrial aquatic world. They can be generated only by equally complex chemical processes,“ states planetologist Assistant Professor Dr Frank Postberg, study director and researcher at the Institute for Earth Sciences at Heidelberg University. The research results were published in “Nature”. (Mehr in: Pressemitteilungen – idw […]

Practically all biochemical processes involve enzymes that accelerate chemical reactions. A research team from the Technical University of Munich (TUM) has now for the first time deciphered the molecular mechanism of the enzyme AsqJ. They see potential applications in the production of pharmaceutically active molecules, for example. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)

How many sorts, in how many copies? The biochemical processes that take place in cells require specific molecules to congregate and interact in specific locations. A novel type of high-resolution microscopy developed at the Max Planck Institute for Biochemistry in Martinsried and Harvard University already allows researchers to visualize these molecular complexes and identify their constituents. Now they can also determine the numbers of each molecular species in these structures. Such quantitative information is valuable for the understanding of cellular mechanisms and how they are altered in disease states. The new technique is described in Nature Methods.

Researchers at UFZ and the University of Queensland have found that the electrification of the white biotechnology is not merely a green dream, but an alternative to petrochemistry with realistic economical potential. Compared to classical sugar based bio-processes, bioelectrochemical processes promise improved yields, which could turn out to be a real game changer. The next generation of bio-production facilities may not only become more environmentally friendly, but also more economically competitive.

Quantum tunnelling is a phenomenon which becomes relevant at the nanoscale and below. It is a paradox from the classical point of view as it enables elementary particles and atoms to permeate an energetic barrier without the need for sufficient energy to overcome it. Tunnelling is being of vital importance for life: physical and chemical processes can be traced directly back to the effects of quantum tunnelling. These processes include the prebiotic chemistry as well as the function of biomolecular nanomachines and has many highly important implications that can be derived from to the field of molecular, prebiotic chemistry and […]

An annual physical typically involves a weight check and questions about unhealthy habits like smoking, but a new study suggests health care providers may be overlooking a critical question: Are you depressed or anxious? (Mehr in: Cancer News — ScienceDaily)

A new test for cervical cancer was found to detect all of the cancers in a trial of 15,744 women, outperforming both the current Pap smear and human papillomavirus (HPV) test at a reduced cost, according to a new study. (Mehr in: Cancer News — ScienceDaily)

The largest population study of hepatitis C in Africa has found three new strains of the virus circulating in the general population in sub-Saharan Africa. The discovery suggests certain antiviral drugs used in the West may be less effective against these strains, and local clinical trials of patients are urgently needed. The study could inform hepatitis C vaccine development and assist the World Health Organization’s aim of eliminating hepatitis C globally. (Mehr in: Cancer News — ScienceDaily)

How does a normal cell turn into a deadly cancer? Seeking an answer to this Question researchers examined the tumor genomes of nearly 300 prostate cancer patients. Their findings describe the ways in which changes in the prostate cells‘ genetic information pave the way for cancer development. Using a newly developed computer model, it is now possible to predict the course of the disease in individual patients. (Mehr in: Cancer News — ScienceDaily)

Exercise has been touted to build bone mass, but exactly how it actually accomplishes this is a matter of debate. Now, researchers show that an exercise-induced hormone activates cells that are critical for bone remodeling in mice. A study identifies a receptor for irisin, an exercise hormone, and shows that irisin impacts sclerostin in mice, a major cellular regulator of bone structure in humans.

No drugs are currently available to treat Ebola, Dengue, or Zika viruses, which infect millions of people every year and result in severe illness, birth defects, and even death. Scientists may finally change that. They identified key ways the three viruses hijack the body’s cells, and they found at least one potential drug that can disrupt this process in human cells.

Researchers have made a significant breakthrough by developing the 3D structure of proteins from inside the eye lens that control how cells communicate with each other, which could open the door to treating diseases such as cataracts, stroke and cancer. (Mehr in: Cancer News — ScienceDaily)

Pseudoachondroplasia (PSACH) is a severe inherited dwarfing condition In PSACH, a genetic mutation leads to abnormal retention of cartilage oligomeric matrix protein (COMP) within the endoplasmic reticulum (ER) of cartilage-producing cells (chondrocytes), which interferes with function and cell viability. Investigators describe how this protein accumulation results in ‚ER stress‘ and initiates a host of pathologic changes. These findings may open up new ways to treat PSACH and other ER-stress-related conditions. (Mehr in: Cancer News — ScienceDaily)
